Abstract: 504,651. Indicating bearings on maps; marching-compasses. WERNER, K. Dec. 11, 1937, Nos. 34392 and 34393. Convention dates, Dec. 12, 1936 and March 15, 1937. [Classes 97 (ii) and 97 (iii)] Relates to instruments which .can be used on a map for determining the co-ordinates'of any point in the map squares, the distance between two points, and the bearing of one point from another, and in the field for marching on a compass bearing. As shown in Fig. 1, the co-ordinate indicating device B comprises two graduated arms at right angles pivoted at the centre of a series of compass graduations on a transparent sheet A carrying a compass D. To enable curved distances to be measured on the map the tips of some of the compass rays arc pointed and arranged so that the distance between adjacent tips is one fifth of the length of a map square. In a modification the compass is mounted at the end of one of the arms of the device B and this arm is hinged to enable the compass to be brought to the centre nf the protractor. In a further modification one arm of the coordinate indicating device is replaced by a scale marked on the protractor and running in the E-W direction. Fig. 4 shows a form in which the co-ordinate indicating device comprises two scales at right angles, marked on the protractor A, which is provided with a series of concentric circles for measuring distances. In the form shown in Fig 7 distances are measured by a cord B secured to the centre of the protractor A. The length of cord may be measured by winding it round the square protractor plate A. An arrow C offset by the amount of the magnetic deviation is provided for use when the instrument is removed from the map and placed on top of a compass.

Filed: 1933-12-14
Abstract: 430,420. Applying capsules &c. CHORLTON, F. O. L., Riverside Works, Bury. Dec. 14, 1933, No. 35164. [Class 125 (ii)] [See also Group XXII] A container such as a bottle or jar is introduced into a sealing-chamber, by means of an auxiliary chamber, which is closed after the can is inserted therein and exhausted of air, and then opened into the sealing-chamber so that it is filled with the inert gas, such as nitrogen, contained therein, the sealing operation, by a cork or cap, then being performed, whereupon the auxiliary chamber is again closed and the gas therein transferred back to the sealing-chamber, and the auxiliary chamber finally opened to atmosphere. As described with reference to a can seaming-machine, the apparatus comprises a vertically movable can support P, an auxiliary chamber M movable against a sealing ring m10, and a main seaming- chamber C with a sealing shutter H, the reciprocating mechanisms being controlled by spaced cams on a vertical shaft as in Specification 430,418, [Group XXII]. A channel v1 communicating with the chamber M when in raised position may be connected by a valve V either to an exhausting pump Q or a pump S for transferring gas from the chamber M to the chamber C, or to atmosphere, whereby the sequence is carried out. In a modification, the chamber M2, Fig. 6, is permanently in sealing engagement with the base of the chamber C, but may be pivoted by a cam m20 and links w26, m27 to bring vertical slots m21, m22 into registration with corresponding inlets and outlets k21, k22, for the can, the sequence of operations being as above. In further modifications the cans are supported in rotating tables, the chambers being brought successively into register with holes leading to exhaust, atmosphere, or the transfer pump. In one such form cans are supported in a rotating table M5, Fig. 10, the chambers being exhausted through a vent v30 after which the can is delivered to the seaming-device 3a, and the gas in the chamber being transferred to the chamber c4 through vents v31, v34. The seamed can is received by a second rotary conveyer, the pockets in which communicate at position 4 with the transfer pump, at 1 with the atmosphere, and at 2 to exhaust. Specifications 381,725, and 403,172, [Group XXII], are referred to.

Abstract: 1402333 Separating film-strip and backing paper EASTMAN KODAK CO 27 July 1972 [29 July 1971] 35176/72 Heading G2X A device for separating a film-strip 2 from the protective paper backing strip 3 comprises a boxlike structure 13 having means 16 for supporting the cassette compartment 7 containing the wound strips, and a slot 18 in a wall portion 17 of the device through which the leading end of the film can be advanced, while the backing strip which curls away, as in Fig. 4, abuts against the wall 17 and is further guided away from the film-strip. The compartment 7 is the take-up compartment of a film cartridge which has been broken open so as to extract the exposed film. It is placed on a spindle 16 in the device 13, which supports it in the correct position, a lip 20 on the compartment engaging a tab member 19 secured within the device 13. A fixed stop within the device serves to locate compartment 7 as a whole. As the leading ends of film-strip and paper strip are withdrawn from compartment 7, the springy nature of the film-strip, and the differing frictional effects on its two sides, cause the paper strip 3 to form a loop 3'. Thus as the leading edge of the film 2 is drawn through the slot 18 in wall 17, the paper strip 3 overlaps the wall 17, as seen in Fig. 4, while the remaining part of the paper strip forms the loop 3', enlarged later to the loop 3", so that the film and paper strips will become completely separated.

Abstract: 394,335. Photographic type-composing. UHERTYPE AKT.-GES., Glarus, Switzerland. Dec. 21, 1931, No. 35281. Convention date, Dec. 19, 1930. [Class 98 (i).] In a method of relating the dimensions of an alphabet or other set of characters to the mechanical displacements produced by the feeding means of a photo-composing machine each set is formed so as to have a standard displacement ratio which is characteristic for it and which may be set on the machine by an index. The displacement index is defined by the formula I =2/3D x (1+R) where I is the required index, D is the ratio of the width A increased by a standard minimum space s, to the height b of a capital " A " multiplied by 100 and R is the ratio of the body height a of an ordinary letter to the overall height d from the bottom of a downstroke to the top of an upstroke. Since the letters are arranged with a horizontal axis corresponding to the centre line M of the body height, a displacement of the base line is required when changing over from one set to another. This displacement L is given by the formula L=2(I2-I1), where I1 and I2 are the indices for the original and substituted alphabets. Specifications 331,305, [Class 98 (i), Photographic cameras &c.], and 358,144 are referred to.

Abstract: 448,468. Batteries. YOUNG ACCUMULATOR CO. (1929), Ltd., MARTIS, H. DE, and CLARK, S. J., Burlington Works, Arterial Road, New Malden, Surrey. Dec. 12, 1934, No. 35741. [Class 53] [See also Group V] An accumulator electrode consists of a plate 3 enclosed in an envelope comprising two sheets of perforated material 1 united round their edges by soft rubber 10 which passes through the perforations at the edges. The sheets 1 may be made of ebonite and may be vulcanized to porous ebonite sheets 2 which may be provided with ribs 18. The sheets 2 may be the same size as the sheets 1 as shown in Fig. 3 or they may be smaller as shown in Fig. 5. Figs. 7 and 8 show a mould for making the electrode. A composite sheet consisting of a sheet of perforated ebonite and a sheet of porous ebonite is placed in the lower part 6 of the mould which is of sufficient size to leave a margin 7 round two sides and one end of the sheet. The plate 3 is then laid on the perforated ebonite sheet in the mould, the plate being smaller than the sheet so that the perforated edges of the latter are exposed. A recess 9 receives the plate lug. A second composite ebonite sheet is then placed over the plate 3 and soft rubber strip 10 is forced by a tool into the space 7. The top plate 11 of the mould which is hinged at 12 to the part 6 is then lowered and the closed mould subjected to heat and pressure. The plate 11 is provided with a block 13 having a flange 14 fitting slidably in a groove 15 which coincides with the margins 7. The rubber softened by the heat is forced by the flange 14 into the marginal perforations of the ebonite sheets. Springs 16 raise the block 13 to its initial position when the pressure is removed preparatory to opening the mould.
